unirse stares JOHN JOSEPH MAHONEY, OF TAUNTON, MASSACHUSETTS.

DOUBLE-ACTING FAUCET.

Application filed August 2, 1921.

To all 'whom 'it may concern Be it known that l, JOHN J. MAHONEY, acitizen of the United States, residing at Taunton, in the county ofBristol and State of Massachusetts, have invented certain new and usefullmprovements in Double-Acting Faucets; and l do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to improve ments in double acting faucetswhich are self-closed for use in the distribution of hot and cold water,and the invention has for an object to provide a simple, compact andinexpensive construction of faucet with 'a double acting valve structureoperable by a single handle and controlling the flow of both hot andcold water, with devices to keep the valves in an open or partially openposition until manually released, whereupon the device is restored tothe initial closed position. V

Another object ofthe invention resides in the provision of a faucet ofthis character, in which independent water boxes are provided incommunication individually with sources of hot and cold water, whereinindependently movable valves are provided to control the flow of waterto a common nozzle or spout.

rlhe invention will be more fully understood after reference to theVaccompanying drawings, in which like parts are indicated by similarreference symbols throughout the several views, and in which Figure 1 isa view in side elevation of an apparatus constructed according to thepresent invention.

Figure 2 is a vertical sectional view therethrough.

Figure 3 is a sectional view taken at right angles to Figure 2; and

Figure 4 is a'sectional view taken on the line 4-4 in Figure 1.

Referring more particularly to the drawings, 1 designates a nozzle orspout which communicates in common with the two water boxes 2 and 3. Apipe 4 in communication with a source of cold water leads to the waterbox 2, while the companion water box 3 is in connection with a source ofhot water supply by a pipe 5.

11 of compressible material which are.A

adapted to seat tightly against the raised valve seats 12 and 13 on theinterior bottom Compressible portions of the water boxes. valve disksand 11 are held on the plungers 8 and 9 as by the screws 14, but, ofcourse, other suitable fastening means may be substituted. The valvedisks 10 and 11 may be thus disconnected from the plungers when worn,and replaced.

Cylinders or sockets 15 and 16 depend from the top plates 17 and 18 ofthewater boxes, and are provided to slidably receive the plungers 3 and9 which reciprocate in a substantially vertical direction, they beingurged normally downward by coil springs 19 and 20, wound about reducedstems 21 and 22 which extend upwardly from the plungers and formshoulders therewith, upon which the lower ends of the springs rest.

Links 23 and 24 connect the upper proljecting ends of the stems 21 and22 with curved t `ms 25 and 26, adapted to be oper-` ated separately bya common centrally disposed handle 27.

As more particularly shown in Fig. 3, the handle 27 is made with abearing sleeve 28 rotatable freely upon a rod'or shaft 29 which ispreferably in the form of a -screw having threads 30 at one end, screwedinto a threaded lug 31, secured-to the top of the device and having itshead 32 disposed on the outside of a second stationary and perforatedlug 33.V rlfhe bearing sleeve 28 is provided with right angularly turnedlugs 34 and 35 which are adapted to engage pins 3G and 37 on the bearingsleeves 38 and 39, respectively, of the curved arms 25 and 26. Vlhisconstruction is most plainly seen in Fig. 4. The arms are upwardlycurved where they connect with the links 23 and 24 to adapt them toswing down in the closing movement of the valve, and to lift freely inraising the valves. Moreover, thev outer overhanging ends of the arms 25and 26 lie beyond the sides of the water boxes and are turned down to alow point in order to connect with bolts or catches 40 and 41 which havea swinging movement about the arms and are adapted to engage with rack'teeth 42 and ii-23 carried at the sides of the waterboxes.

In the use of the device cold water from the pipe t constantly occupiesthe water box 2, while hot water received through the opposite pipe 5 iscontained in theAadjaCent` water box 3, but neither supply of water ispermitted to descend into the faucet l because of the initially closedposition of the two valves. Y

The springs l9'and 2O are responsible for this closed position, and theyrestore the val-ves: to their seats after-'each opening' thereby causingthe lugBLt'to ride downward against'the pin 36 and raise the arm 26.'

I/Vith' the arm, the valve plunger 9 is also lifted and hot water maythen descend through the ports 7 and issue from the faucet l. Theengagement of the pawl or'Y catch 41 with the rack teeth i3will'pr'event the immediate return of the valve to its'seat by Y reasonof the influence ofthe spring 20, ant

consequently the device may be kept V in this position withoutthe-continued attendance of the operator. `When a sufficient supply ofwater has'been had, the catch il is released and the valve 9automatically closes.A By
